HP MSM7xx Management And Configuration Manual page 87

A static NAT mapping allows only one internal IP address to act as the destination for a
particular protocol (unless you map the protocol to a nonstandard port). For example, you
can run only one Web server on the internal network.
Note
If you use a NAT static mapping to enable a secure (HTTPS) Web server on the internal

network on TCP port 443, remote access to the management tool is no longer possible,
as all incoming HTTPS requests are routed to the internal Web server and not to the
management tool. You can change the default management port (TCP 443) to an
alternate unused TCP port in this case.
 If you create a static mapping, the firewall is automatically opened to accept the traffic.
However, this firewall rule is not visible on the Firewall configuration page (it is
maintained internally by the controller).
Common applications are affected by NAT as follows:
Application
FTP (passive mode)
FTP (active mode)
NetMeeting
Telnet
Windows networking
The controller provides pre-configured static mappings for most common applications,
which you can enable as needed.
Most Web browsers use FTP in active mode. Some browsers provide a configuration option
that enables you to alter this. Use the following steps to change this behavior in Microsoft
Internet Explorer.
1. Select Tools > Internet options to open the Internet options dialog.
2. Select the Advanced tab.
3. Under Browsing, enable the Use Passive FTP for compatibility with some firewalls
and DSL modems checkbox.
